Persistent Names for Network Interfaces in Linux Mint 21.3: A Predictable Naming Scheme

Persistent Names for Network Interfaces in Linux Mint 21.3

In Linux Mint 21.3, as in other Linux distributions, network interfaces can be assigned persistent names to ensure that they are consistently named across reboots. This is especially useful for systems that often have PCIe devices added or removed, as it allows for a predictable naming scheme.

Predictable Naming Scheme

The predictable naming scheme for network interfaces in Linux Mint 21.3 is based on the physical location of the device on the board and the type of device. The naming scheme uses the following format:

Where:

• en stands for Ethernet
• p stands for PCIe
• X is the number of the PCIe slot, starting from 0 at the top of the board
• s stands for the type of device, such as s for a standard Ethernet device
• Y is the number of the port on the device, starting from 0

Implementing Persistent Names

To implement persistent names for network interfaces in Linux Mint 21.3, you will need to edit the /etc/network/interfaces file. This file contains the configuration for all of the network interfaces on the system.

To assign a persistent name to a network interface, you will need to add a line to the /etc/network/interfaces file that looks like this:

Where enpXsY is the persistent name you want to assign to the interface.

For example, to assign the persistent name enp0s25 to the second Ethernet port on the first PCIe device, you would add the following line to the /etc/network/interfaces file:
